As soon as the wireless sensor is receiving power, the red pilot light will light up and thus display that data is being transmitted to the base unit. 3. Put the battery compartment cover back in place.
- Do not use batteries that have a voltage that is too low (only 1.2 V instead of 1.5 V). This affects the accuracy of the measurements, among other things.
- If possible, use alkaline batteries instead of zinc-carbon batteries. Alkaline batteries last longer, particularly outside in low temperatures. Using addition wireless sensors The device comes with one wireless sensor. However, you can operate it with up to three wireless sensors. Additional wireless sensors are available via our online shop. The wireless sensors can be located in different rooms or outdoors. Every sensor must be assigned its own sensor number (= number of the transmission channel) (1 to 3). For the snow and frost warning, the base unit only analyses the information from the sensor with the lowest number (by default 1). If only one sensor is connected to channel 1, 2 or 3, the display will function on all 3 channels. Procedure:
1. Remove the battery compartment cover on the back of the wireless sensor. 2. Set a different sensor number for each wireless sensor with the sliding switches. 3.
